Antimicrobial resistance is everywhere and has the potential to affect anyone, of any age, in any country. A new study published in Nature and made at the Helsinki University investigated potential sources of antibiotic resistance genes in the infant gut. According to the study infants carry more resistant bacteria in their gut than adults do, irrespective of whether they themselves have been treated with antibiotics or not. Babies who have been breastfed for at least six months, have lower abundances of resistance genes compared to babies who aren’t breastfed. Drug resistant infections in infants and children are a growing threat. It has been estimated that more than 200 000 infants die annually due to resistant septic infections.
